SAFETY DEVICE FOR LANTERNS.

SPECIFICATION forming part of Letters Patent No. 611,858, dated October4, 1898.

Application filed June 23, 1898. Serial No. 684,207. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANCIS H. DEWEY, of Reading, inthe county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Safety Devices for Lanterns, of which thefollowing is a specification.

This invention relates to oil illuminating apparatus, and moreparticularly to the ordinary type of hand-lantern. The invention has forits object to provide means whereby the oil-reservoir may be closed orits outlet materially restricted when the lantern is tilted or placed onits side through accident or other cause.

The invention consists in the novel features of construction andarrangement which I shall hereinafter describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of a lantern, with parts insection, illustrating my improvements. Fig. 2 represents a similar viewshowing the lantern on its side. Fig. 3 represents a section on line 3 3of Fig. 1. Fig. 3 represents a similar view showing the position of theshutoff slide when actuated by the tilting of the lantern. Fig. 4represents a sectional view, on a larger scale, of the lower part of thelantern. Fig. 5 represents a similar .view of a lantern in a tiltedposition. Fig. 6 represents a sectional view taken at right angles tothe section in Fig. 4:.

The same reference characters indicate the same parts in all thefigures.

Referring to the drawings, a designates the oil-reservoir of thelantern, the same having a base-flange a formed at its lower margin. 1)designates the tubular frame, 61 the bail, c the protective cage, 6 thechimney, and f the burner, all of said parts being of the usual or anydesired construction and needing no further description.

The top of the oil-reservoir is formed-with an outlet-aperture a throughwhich the wick- 9 passes into the burner above. Below this 71?, whichnormally registers with the outlet a of the oil-reservoir, said platebeing also weighted with pieces of metal 71 h Since it is desirable tohave the outlet a somewhat larger than the wick g in order to let thelatter pass freely therethrough, there is sufficient space left to allowthe oil to escape when the lantern lies on its side, as in Fig. 2, or istilted from a substantially perpendicular posture. Such tilting orupsetting of the lantern frequently occurs through accident ,or othercause, and the result is that the oil flows out of the reservoir. Myinvention prevents this, however, for when the lantern is tilted or lieson its side the slide it automatically assumes a position, such asillustrated in Figs. 2 and 5, across the outlet a the weights h hassisting in moving it from its normal position to its abnormalposition. When in said abnormal position, the slide covers or materiallyrestricts the aperture (1 and pre 'vents the outflow of oil which wouldordinarily occur. The mounting of the slide is preferably such that itwill be actuated in almost any abnormal position of the lantern.

. Having thus explained the nature of my invention and described away ofconstructing and using the same, although without having attempted toset forth all the forms in which it may be embodied or all the modes ofits use, I declare that WhatI claim is- 1. In a lantern, the combinationwith the oil-reservoir having an outlet through which FRANCIS DEWEY.
